What could this "Unknown Device" be?

[MPalmz]

My vLited OS is trying to install drivers for "unknown device." Since I removed all drivers for my ISO and just install drivers from my chipset disk, it can't find the driver for it and asks for me to insert the manufacturer's disk. But even then Vista can't find drivers for the device. When I go into device manager the properties for the Unknown Device say that it's location is "on PCI standard ISA bridge."

My guess is that it's really not that important, and to avoid windows trying to get drivers for it every time I restart I've just disabled it for now. Anyone know what this could be?
